These stable trekking packs have also undergone a complete transformation. With luxurious back padding and top-notch features, these packs are comfortable load transporters, tough provision chests and neat gear stores, all rolled into one. The pivoting Vari Flex fins hold the load firmly in place. Combined with the X-frame and the Vari Quick system they form a carry system that will take medium to heavy loads, whilst maintaining stability, flexibility and optimum load transfer. With its new back-padding layout, the [1]Air contact System sits even more comfortably on the back, while at the same time optimising the airflow. The SL models, specifically designed to suit the female form, are the ultimate in back pampering for women on tour.
